SS3P3-M3/85A

Single Diodes Overview

The SS3P3-M3/85A is a high current density surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a single circuit configuration in an SMP (DO-220AA) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 30 V and a maximum average forward rectified current of 3.0 A. The device exhibits a typical instantaneous forward voltage of 0.43 V at 125 °C and a peak forward surge current capability of 50 A. Operating junction and storage temperature ranges from -55 to +150 °C.

Single Diodes Feature Summary

• Very low profile construction with a typical height of 1.0 mm, suitable for automated placement.
• Low forward voltage drop resulting in reduced power losses and high efficiency.
• Low thermal resistance for effective heat dissipation.
• Meets MSL level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C.

Single Diodes Applications

• Low voltage high frequency inverters
• Freewheeling applications
• DC/DC converters
• Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The /85A designation indicates a base quantity of 10,000 units delivered in a 13-inch diameter plastic tape and reel format. Confirm compliance requirements such as RoHS status and halogen-free material categorization directly from the manufacturer's datasheet before procurement.

Single Diodes Selection Notes

Select this component for applications requiring a 30 V rating and 3.0 A continuous current handling in a compact surface-mount form factor. Consider the thermal characteristics, specifically the junction-to-ambient thermal resistance of 95 °C/W, when designing the PCB layout. Ensure the operating environment stays within the specified -55 to +150 °C junction temperature range for reliable performance.

Single Diodes Part Context

This part belongs to the eSMP series of high current density surface-mount Schottky barrier rectifiers. The 'M3' suffix denotes that the device is halogen-free, RoHS-compliant, and meets commercial grade standards. It utilizes matte tin plated leads which are solderable according to JESD 22-B102 standards.

Single Diodes Replacement Considerations

The automotive grade equivalent is the SS3P3HM3/85A. Verify package compatibility and electrical ratings when substituting with other Schottky rectifiers in the SMP (DO-220AA) footprint.
